摘要
为筛选经济、资源节约型容器育苗基质,采用草炭土、秸秆粉、有机肥、河沙、珍珠岩、蛭石材料,按不同比例配成4种配方基质,以常用商用配方基质(珍珠岩∶蛭石∶草炭=1∶1∶1)为对照,进行刺槐容器播种育苗试验,测定不同配方基质下种子发芽出苗率、幼苗生长指标(株高、生物量、地径等)。结果表明:不同配方基质下刺槐种子出苗及其前期生长情况不一;其中T2配方(草炭土∶沙子∶有机肥∶蛭石=1∶1∶1∶1)基质刺槐种子发芽种苗出苗率及幼苗生物量、苗高、地径、根长等与对照间没有显著差异,可以作为刺槐容器播种育苗基质。
In order to select economical and resource-conserving substrates for the container seedling breeding of Robinia pseudoacacia L.,peat,straw powder,organic fertilizer,sand,perlite and vermiculite were selected as materials to mix with different proportions to form 4 substrate formulations,which were used as growth media to study their effects on the growth of container-grow-seedling breeding of Robinia pseudoacacia L.by test the germination rate,young seedling height,root length and root collar diameter.The common commercial substrate（perlite∶vermiculite∶peat=1∶1∶1） was used as a control group.The results showed that the emergence rate of young seedlings,and their growth condition for different substrates had significantly difference.The seedlings cultivated in second substrate formulation（peat∶straw powder∶organic fertilizer∶vermiculite = 1∶1∶1∶1） showed great growth,and their biomass,seedling height,root length were similar to the control group,which could serve as a economical and practical nursery-type substrate for container seedlings of Robinia pseudoacacia L..
